Mr. Whitely's specimens of this species were obtained at 

 an elevation of 6000 above the sea, in the forest-clad slopes 

 leading to the cliffs of Roraima. The bird is certainly nearly 

 allied to E. gularis, of which we have specimens both from 

 Brazil and also from Bolivia. The colours of the plumage 

 are similarly distributed^ but are all much deeper in tint.

Mr. Whitely's collection contains only a single male speci- 

 men of this peculiar bird, which he shot at an elevation of 

 5000 feet above the sea, on the slopes of Roraima. 



In coloration L. nigrifrons has no near allies, the black 

 band across the forehead being quite peculiar. The long 

 rictal bristles and the rather straight narrow bill and compa- 

 ratively long tail seem to indicate its place in the genus 

 Le'ptopogon, but we are in some doubt on this point.
